MEANS FOR LUBRICATING SHAFTING.

Application filed October 18, 1907, Serial No. 398,112. Renewed February20, 1909.

Specification of Letters Patent.

Patented April 27, 1909.

Serial No. 479,268.

To all whom it may concern:-

Be it known that I, JAMES BARRY, a citizen of the United States,residing at Ocean View, in the county of San Francisco and State ofCalifornia, have invented certain new and useful Improvements in Meansfor Lubricating Shafting and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to improved mechanism for lubricating sha'ftingand particularly to mechanism for continuously distributing lubricant inproximity to the circumference of the shafting.

The invention consists of the production of a hollow shaft or axle, orone formed with a hollow portion for accommodating a wick designed toconduct lubricating material from a suitable receptacle to the bearingproper, and means for holding the wick in proper posi tion.

The invention further consists in certain novel constructions,combinations and arrangements of parts, which will be hereinafter morefully described and claimed.

In the accompanying drawings: Figure l is a sideelevation of a shaft oraxle provided with my self lubricating device. Fig. 2 is an end viewshowing an inlet for forcing lubricant into the axle. Fig. 3 is alongitudinal vertical section. Fig. l is a section on line 44 of Fig. 3.Fig. 5 shows the bar for regulating the position of the wick.

Referring more particularly to the drawings, 1 is a hollow shaft adaptedto receive and contain the wick 2. In effect axle 1 is substantially atube having one end provided with an opening 3, through which lubricantis designed to be forced, and the other end closed by a cap 4. Theaperture 3 is designed to be covered by a swinging member or disk 5 forpreventing any foreign matter from entering the axle. The screw-threadedcap 4 permits of easy access to the interior of the axle, and in orderto provide means for preventing any lubricant from escaping, a packingis interposed between the end of axle l and the'said cap. Passingthrough the cap and packing is a centrally located shaft or spindle 7provided with lugs or barbs 8, the lugs or barbs designed to engage oneend of the wick 2, so that when the spindle 7 is turned the wick will bewound as shown in Fig. l, one end being allowed to project above thesurface of the axle through aperture 9. The spindle 7 is journaled atone end in the member 10.

A suitable stop or lug 11 is secured to shaft 7 so as to prevent packing6 from accidentally becoming displaced and leaving its correct positionin cap 4. The slot 9 may be the full ength of the shaft, or severalindividual slots may be positioned at proper intervals along the shaft.In any case the spindle 7 will extend the full length of the shaft andwill ongage all of the wicks employed. A set screw 12 in a flange on theleft hand end of the shaft may be used to hold the shaft from turning inits supports.

In constructing a shaft with a slot as 9, wick 2, and means for holdingthe same in position, a device is provided in which lubricant isdesigned to be fed by capillary attraction to the inner surface of thehub. In the case of horizontal shafts, the slot 9 is preferably locatedon the upper side, in order to prevent the oil from flowing from thelubrieating chamber except under the influence of ca illary attraction.

Vhat I claim is In a device of the character described, a hollow shaftformed with an opening in the side thereof, one end of the shaft beingsolid, a cap located on the opposite end of the shaft, a centrallylocated longitudinal spindle within said shaft, said spindle journaledat one end in the cap and accessible from the exte-- rior, means forpreventing the longitudinal movement of the cap, engaging devices on thespindle, a wick projecting from the opening in the side of the shaft andengaged by said spindle.

In testimony whereof I affix my signature in presence of two witnesses.

JAMES BARRY.
